Quentin Adam from Clever Cloud discusses immutable infrastructure and automation. He argues that infrastructure should be treated as ephemeral instances rather than precious servers. Stateless applications deployed across immutable instances in an automated fashion provide scalability, high availability, and security. Key aspects include splitting state from process, service discovery, configuration as code, distributed systems, and monitoring.
